INcLINnBI-.E WINDOW.

Application led January k18, 1926. Serial No. 82,021.

'This invention relates to improvements in window construction as applied to dwelling houses, oce buildingsl and the like and has as one. of its objects the provision of a, window sash'pivoted to swing outward between a pair of stiles, slidable within the sash within the window frame, the axis of the sash being at its extreme lower edge.

A further feature is to provide a swinging sash so'arranged in connection with its sliding stiles that the latter'are positively main'- tained in proper adjusted position, inseparably from the sash.

Another aim is to produce a swinging sash having spring counterbalancing means whereby muscular effort in moving the sash upon its pivot is materially reduced.

A still" further object is to provide spring actuatedy catches to retain the sash when closed between its Stiles, these catches being arranged in such manner as to prevent re- -lease of the sash except by use off-,both hands of an operator and are substantially inoperable by children.

These several valuable objects are accomplished by the novel and practical construction of parts hereinafter described and de-` lineated in the drawing, formingan essential part of this disclosure, and in which:-

Figure 1 is a partial front elevational, partial sectional view showing a corner of a window made in accor-dance with the invention.

Figure 2 is a sectional view taken 2-2 of Figure 1.

Figure 3 is another view like Figure 1, illustrating a modification in construction.

Figure A is a view similar to Figure 1 showing a further modification of the same.

Figure 5 is a sectional View taken on line 5 5 of Figure 4.

Figure 6 is another front and sectional view in which a further adaptation of the device is shown and also the latch connect- -ing the sash and stiles.

Figure 7 isa Jfragmentary View showin an alternative type of sash and stile engaging means. f-

Throughout the several views a transparent window pane, such as glass, is designated by the numeral 10, the same being secured by usual glazing methods in a sash frame 11 of' ordinary construction except that its side members are rabbeted lengthwise at their rear outer edges, as best'seen on line in Figure 7,' to engage4 the correspondingly projecting tenon-like elements 12 of a pair of stiles 13 one. on each side of the sash and equivalent in length therewith.

rlhe stiles 13 are slidable between guide cleats 14 secured in pairs on the inner surfaces of the window frame side members 15, which are connected at their upper and lowerends to the upper rail beam and sill respectively of the window.

A simple form of the device lis shown in Figures 1 and 2, in which the lower member of the sash is formed with a longitudinal groove 16 at the center Vof its width, the groove registeringwith similarv grooves 17 in the lower ends of the stiles 13.

A rod 18 of circular cross section is disposed in these grooves and retained therein by a flat sheet metal plate 19 held to the lower edge of the sash by fastenings 20.

The ends of the rods 18 are flattened and bent at right angles,v as at 21, to fit into corresponding grooves formed centrally in the outer sides of the stiles 13 where they are secured by screws 22.

It will 4now be seen that the rod 18 acts as a hinge element on which the window sash may pivot `when swung forward, valso as a connecting member between the sash and Stiles, and further, maintains the stiles in` proper spaced relation, besides causing them to positively move up and down in conformity with any sliding movement imparted to the window sash.

Substantially the same arrangement is in-4 dicated inFigure 3 except in place of the groove 18, a groove 23 is formed of increased sectional area, and the rod 18 is encircled by a pairv of oppositely wound torsional springs 24, 'their inner adjacent ends l25 being secured in the plate 19 and their outer ends 26 set in the lower ends of the Stiles 13, the effect being to exert pressure on the sash to move it into a closed position, as will be understood.

ln a similar manner the device shown in Figs. 4 and 5 acts to normally closel the sash against the abutments 12 of the Stiles. lin this case grooves 27 are formed in the lower member of the sash frame vat each end .and 'disposed therein are torsional springs 28,

retained by the plate 19, the inner ends 29 of thesprings being xedin the sash and theouter ends 30 being similarly fixed in the In this device the axes of the springs correspond with the pivotal axis of the sash and the springs not only serve as hinge membe1s,but normally press the sash into closed position, and in addition the tension of the springs act to draw 'the stiles against the sides of the sash.

Figures 6 and 7 show a structure incorporating the features of Figures 3, 4 and 5 invaddition to others of practical merit.

In this case the sash is grooved itsfull length, as at 3l, and disposed therein are oppositely wound torsional springs 32 and 33 retained by the plate 19 as previously described.

The inner ends 34 are loosely inserted into an openingr 35 at the center of the sash and their outer ends 36 bent at right angles to pass into recesses 37 in the outer faces of the stiles and be held rigidly therein byclips 38.

In this case the springs perform a threefold duty.; to act as a hinge element, to close or assist closing the sash, and to retain the.

stiles and sash in intimate contact.

These last named figures also show a pair of catches designed to hold the sash when in a closed position and prevent inadvertent opening of the same.-

These catches are composed of a flat strip 40 provided with lugs 41 held in the upper member of the sash frame by a pivot 42. At the inner ends of these strips are knobs 43 by which the catches may be tilted on their pivots, the sash being cut out for that purpose and compression springs 44:, set in the sash, retain the catches in operative posil tion.

Near the outer ends of the strips, on their undersides, are detents 45 to engage in ap: propriate openings in the upper ends of the stiles, over which the strips extend.

These detents are bevelled on their rear, engaging sides, so that when the sash is closed against the stiles, the catches will rise until complete closure has been eifected, whereupon the springs 40 will force the detents into engaging position.

It will be seen that in order to release the sash from the stiles, that is to swing the sash forward, both catches must be manipulated requiring the use of both hands, thus reducing accidental loosening of the sash, and also that the knobs 43 serve as handles by which the sash may be readily drawn forward'.

Obviously the springs will be suited to the weight and type of the window and may be used Vwonly as buffers, partially counteracting the forward movement-of the sash, or be suiiiciently strong to close the same with little or no effort on the part of an operator.

While certain preferred embodiments of `this device have been shown and described, ithwill be understood that changes in the forin, arrangements, proportions, sizes and details thereof may be made without departing from the scope of the invention as delined in the appended claims.`

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
